Abstract Electromagnetic wave (EMW) absorbing materials play an increasingly crucial role in mitigating electromagnetic pollution. In this study, the laser‐induced self‐propagating synthesis (LSS) method was employed to successfully produce Al 3 BC powders with a purity of up 98.8 wt.% using aluminum powder, boron carbide and carbon powder as raw materials. The preparation efficiency increased by approximately 20–360 times compared conventional heating methods. Additionally, as‐synthesized exhibited remarkable oxidation resistance, apparent activation energy ( E ) 213.04 kJ/mol preexponential factor 5.38. Moreover, demonstrated superior EMW absorption performance at 973 K, reflection loss below –10 dB within frequency range 6.74–7.97 GHz minimum reaching –45.86 thickness 2.9 mm. These results suggest that is promising candidates for high‐temperature applications.

Abstract Multifunctional electromagnetic wave (EMW) absorbing materials are attracting attention because of their potential applications in medical, livelihood, and military. In this study, a pomegranate‐like nanolayer featuring core‐shell architecture (PNCS) is prepared using confinement strategy. Introducing metal atoms into unique design (M‐PNCS, M = Mn, Fe, Co, Ni, Cu) effectively tuned the response improved functions. The Mn‐PNCS composite exhibited highest absorption. Its reflection loss ( RL ) reached −62.39 dB with an effective absorption bandwidth (EAB) at 1.8 mm 6.0 GHz. As charge transport capacity increases, its can be transformed shielding, green shielding index up to 3.54. On basis, used fabricate multifunctional film new strain sensor. This integrated absorption, thermal insulation, hydrophobicity, flexibility, sensing, thus showing for use wearable protective clothing. addition, sensors simulation achieved sensing through coupling effect between patterns. These findings demonstrate that excellent material technical fields EMW devices.
